Let I = [a,b] be a finite interval. Show that the space C(I,R^n) of continous functions from I into R^n is a Banach space with the uniform norm llull = sup l u(t) l where t is in I. (Show that this is a norm and that C(I,R^n) is complete) See attached file. Please be very detailed when answering question.
